It's a help wanted ad for flight attendants that looks straight out of the 1950's. Except that it was posted on Facebook just a few days ago.

Bangkok-based Nok Air is looking for a few good flight attendants. As long as they are females aged 25 and under; at least 5 feet, 3 inches tall; proportionate in their height and weight; and do not wear dental braces. Resumes must be submitted in English, accompanied by the applicant's height and weight and two photos: a two-inch "formal photo" and a full-length photo in a "casual dress."

The ad, posted on the airline's Facebook page and first spotted by Jaunted, has 542 "likes" so far.

But don't get it twisted: Nok Air is looking for more than just a pretty face. Applicants must also have a bachelor degree or higher, "excellent communication skills both in Thai and English," and be friendly and professional. Cabin crew experience is an asset. Being able to swim 50 meters is a requirement.

The low-cost airline flies to destinations in Thailand in Malaysia under the tag line "We Fly Smiles." The web site features many young and attractive female employees, many giving the "thumbs up" sign in the photos. The airline could not be reached directly for comment.

Deadline for applications is March 24.
